Oil and Washer fluid questions...
Also, does anybody know where to get genuine MB windshield fluid other than the Dealer? I like the fluid because it foams up really good when washing the windshield and lights. I'm sure MB asks like $50 for a bottle of it.
I did see this post earlier today. But it doesn't really mention what oil weight is from the factory.
"As far as the correct oil is concerned, the oil MUST conform to the MB-229.5 specification. However, the correct viscosity and type used by the factory in our GLK is Mobil-1 Formula-M 5w-40. This oil must be used year round and can ONLY be purchased at the dealer for now.
WARNING: Please do not confuse this oil with Mobil-1 ESP Formula-M 5w-40. They sound alike but they are NOT THE SAME. ESP is for diesel engines ONLY! Also, please DO NOT GET the “over the counter” straight Mobil-1 5w-40 either. This oil does not meet the strict Mercedes Benz 229.5 spec."
But to top it off, say 1/2 quart or less, any full Mobil-1 syn. multi grade will do.... more than that please see above.

How about wipers, those in OEM form suck, mine started squeaking after 4 months (summer months, and I park in garages). I'm not the only one with this. Gonna get Bosch or PIAA after winter.

More and more companies are now producing Syn Oil that meets the MB-Spec... it's basically a different ratio mix of additives (multi-weight extenders) etc...
Both US and Canadian GLK's use 8.5 qts or 8L of oil with filter change... Please read your owners manual... ?????? Refer to page 334.
the concentrate for the windshield washer is 3.69 each.
so all in all pretty cheap.
Firstly: The price - in my country we pay $ 13,5/litre ($ 13,5/,2642 US gallons)

Secondly: Unlike the US GLK Operator's manual, is mine with regard to the chapter "Washer system and headlamp cleaning system", having a: "! Highlights hazards that may result in damage to your vehicle.". In short state it that use of an improper concentrate may cause harm to the headlight plastic lenses. As I read it, are not all brands to be used uncritically. Meaning: A certain concentrate or a different washer fluid may cause graceful (i.e. over time) degradation of the lenses. This was as well one of the few issues the dealership mentioned when we picked up the new GLK.

Therefore the formula MUST be made for the polycarbonate lenes of your headlights as well. Read the instructions, and alcohol in the formula is a NO-NO.
The cars from the factory, except AMGs, actually come with some kind of Shell Synthetic oil, strange I know, but they have some contract with Daimler.
Just use the Mobil 1 0w40 to top up, and it will be fine.
The washer fluid fill ups aren't that much money from the dealer. ALso, when you have service, they always top mine to the top (which is odd as I never use it. I feel it's bad for paint and whatnot).
